upgrades failing on selfregistered com objects

[TurboFisch]

HI,

upgrades failing on selfregistered com objects.

1) install version 1.0 - all files there
2) install version 2.0 - all files except self-registered dlls are there
3) install version 2.0 - again and the self-registered dlls are installed

upgrade scenarios in the upgrade table is to uninstall first before installing the new version

log files do not show any error other than the absence of the files are want installed.

Any ideas on why this weird behavior is happening?

thanks,

workaround #1 - set the file to "overwrite". have to do for each file
workaround #2 - disable e"small/minor updgrade settings.
